Ukuxuba irabha yeyona nkqubo inamandla kakhulu kwiifektri zerabha.Ngenxa yobuchule obuphezulu kunye nomatshini wokuxutywa, sesona sixhobo sisetyenziswa kakhulu kunye nesona sixhaphakileyo sokuxuba irabha kwishishini lerabha.Uxuba njani iimveliso zerabha?
Apha ngezantsi sijonga inkqubo yokuxuba umxube ukusuka kwigophe lamandla:
Inkqubo yokuxuba umxube
Ukudibanisa i-compound kunye ne-mixer (ebhekisela kwicandelo lokuxuba) inokwahlulwa ibe ngamanqanaba ama-4.
1. Faka irabha yeplastiki kunye nezinto ezincinci;
2. Yongeza izinto ezinkulu kwiibhetshi (ngokubanzi zongezwa kwiibhetshi ezimbini, i-batch yokuqala yokuqinisa inxalenye kunye ne-filler; i-batch yesibini yinto eseleyo yokuqinisa, i-filler kunye ne-softener);
3. Ukucokiswa ngakumbi, ukuxuba, kunye nokusasaza;
I-4, ukukhutshwa, kodwa ngokuhambelana nalo msebenzi wendabuko, kuyimfuneko ukuthatha iibhetshi ezininzi ze-dosing, i-bolt ephezulu yokuphakamisa kunye nokuvulwa kwezibuko lokutya kunye nokuvala rhoqo, ukuguqulwa kwenkqubo kuninzi, okukhokelela kwixesha elide lokungenzi nto.
Amacandelo amabini 1 kunye ne-2 njengoko kubonisiwe kwi-akhawunti yomzobo malunga ne-60% yawo wonke umjikelo.Ngeli xesha, izixhobo zisebenza kumthwalo ophantsi kwaye izinga lokusetyenziswa okusebenzayo lihlala lisezantsi.
Ilinde ukuba ibhetshi yesibini yezixhobo zongezwe, umxubi utshintshelwe ekusebenzeni komthwalo ogcweleyo, obonakaliswa kulo mfanekiso ulandelayo ukusuka ekuqaleni kwe-3, ijika lamandla liqala ukunyuka ngokukhawuleza, kwaye liqala kuphela ukwehla emva kwexesha elithile.
Inokubonwa kumzobo wokuba ngaphambi kokuba esinye isiqingatha se-ejenti yokuqinisa kunye nokuzalisa isetyenziswe, nangona umjikelezo wonke uhlala ixesha elingaphezu kwesiqingatha sexesha, indawo yokuzaliswa kwegumbi lokuxuba ayiphezulu, kodwa izinga lokusetyenziswa kwesixhobo somxube wangaphakathi alilunganga, kodwa lihlala.Umatshini kunye nexesha.Inxalenye enkulu yexesha yayixakeke ngokuphakanyiswa kwebholithi ephezulu kunye nokuvulwa kunye nokuvalwa kwezibuko lokutya njengexesha elincedisayo.Oku kufuneka kukhokelele kwezi meko zintathu zilandelayo:
Okokuqala, umjikelo uhlala ixesha elide
Ekubeni inxalenye enkulu yexesha iphantsi komthwalo ophantsi, izinga lokusetyenziswa kwesixhobo liphantsi.Ngokuqhelekileyo, ixesha lokuxuba umxube wangaphakathi we-20 rpm yimizuzu eyi-10 ukuya kwe-12, kwaye ukuphunyezwa okuthe ngqo kuxhomekeke kubuchule bomqhubi.
Okwesibini, ubushushu bekhompawundi yerabha kunye ne-Mooney viscosity iyaguquguquka kakhulu.
Ekubeni ulawulo lomjikelo alusekelwe kwi-viscosity efanayo, kodwa lusekelwe kwixesha elimiselweyo okanye ukushisa, ukuguquguquka phakathi kwebhetshi kunye nebhetshi kukhulu.
Okwesithathu, umahluko ekusebenziseni amandla phakathi kwezinto kunye nezixhobo zinkulu.
Ingabonwa ukuba umxube womxube wemveli awunayo imigangatho yolawulo yenkqubo efanayo kunye nethembekileyo, okukhokelela kumohluko omkhulu ekusebenzeni phakathi kwebhetshi kunye nebhetshi, kunye nenkcitho yamandla.
Ukuba awuyi kuqwalasela inkqubo yokulawula umxube, lawula ukusetyenziswa kwamandla kwinqanaba ngalinye kunye nesigaba somjikelezo wokuxuba i-rubber, kuya kuchitha amandla amaninzi.Isiphumo singumjikelezo omde wokuxuba, ukusebenza kakuhle kokuxuba kunye nokuguquguquka okuphezulu komgangatho werabha..Ngoko ke, kwifektri yerabha usebenzisa umxube wangaphakathi, indlela yokunciphisa ukusetyenziswa kwamandla ngumsebenzi oqhelekileyo phantsi kwesiseko sokuqinisekisa umgangatho wokuxuba.Gweba ngokuchanekileyo kwaye ulawule ukuphela komjikelo wokuxuba ukuphepha ukwenzeka "kokucokisa ngaphantsi" kunye "nokucoca ngaphezulu".
